It is possible for many types of devices to have wireless connections to the Internet and to physically move in their environment, there is a difference between a mobile device and a mobile connection with the distinction being whether the device uses changing connections to remain connected to the Internet or not. Hence if a user uses the same wireless access point to remain connected to the Internet, they are not considered a mobile user as the wireless point is fixed. A mobile node would be one where its access point changes in order to keep the connection.
